Be it known that I, J ULrUs EHRENFEUCH- TER, a citizen of the German Republic, and resident of Hanover-lVulfel, Germany, have 5 invented certain new and useful Improvements in Parallel Vises (for which I have filed applications in Germany, March 22,1918, Nos. 312852, 328326; England (assigned to H. Pedersen), March 28, 1919, No. 133898 Canada, April 30, 1919, No. 201-122; France, April 14:, 1919, No. 5181 15; Belgium, May 10, 1919, No. 280272; Switzerland, May 30, 1918, No. 81658; Austria, May 31, 1918, No. 80939; Hungary, June 6, 1918, No. .76:- 15 403; Holland, February 27, 1919, No. 534.19"; Italy, March 22, 1918, No. FF105; Spain, March 22, 1918, No. 73171; Sweden, March 15, 1919, No. 51511 Norway, March 21, 1919, No. 33252; Denmark, March 13, 1919, 0 No. 25536; Czechoslovakia, June 28, 1919,

No. 1255), of which the following is a specification.

This invention relates to an improved parallel-vise of the type having a U-shaped frame and vise-jaws guided on the headplanes thereof, the novelty consisting in the particular construction of said vise.

in the accompanying drawing: Figs. 1, 2 and 3 are respectively a sectional side view, a side view, and a front view, of the improved vise, while Fig. 4 is a horizontal section of the U-shaped frame.

The integral U-shaped frame A of T- section (Fig. 4-) carries on its head-planes B and C of equal level two vise-jaws D and E, which are guided thereon in dovetail fashion (Fig. The front jaw D can be adjusted by a pressure-spindle F, which is rotatable in the front member ofsaid frame and which does not extend into the space G between the parallel lateral members thereof. The rear E can be ad- I justed by hand and'locked in position by a laterally withdrawable pawl H, which passes'through a boring in said frame A' and which engages in a rack I on the underside of said jaw E. The U-shaped integral frame A hasrather long parallel lateral members so as to extend deeply below the axis of the spindle F and thus to afford a deep downwardly extending space G for' the reception of large work-pieces in'the vise, while it is provided with a hole K in its lower end land 4-) for a passage of bars and rods therethrough, which are to be worked in'the vise.

lVhat I claim, is

A parallel-vise comprising, in 00111131113: tion, an integral U-shaped frame of T-section having long parallel lateral members and a passage-hole in its lower end, head planes, of equal level on said frame, a front vise-jaw and a rear vise-jaw guided on said head-planes in dovetail fashion, a rotatable pressure-spindle in the member of said frame and engaging the front vise-jaw only, a rack on the underside of the rear vise-jaw, and a laterally withdrawable locking-pawl in said frame located to engage said rack, si'ibstantially as 70 set forth. a

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
